LRF Laser Range Finder Attachment for Mate Series MAH50
LRF can be equipped as an optional accessory. In addition to facilitating accuracy, the LRF extension can work as a power bank to prolong the 4-hour battery life for MATE.
Laser rangefinder module (LRF) - Long awaited by many hunters, the MATE has a separately purchased laser rangefinder module. The module is attached to the outside of the attachment by means of a short Picatinny rail, which is mounted on the MATE. Small gimmick: The LRF is itself a power bank, which is equipped with a commercially available type 18650 battery. So if the hunter is in possession of the LRF module, it serves as an external battery, so that the enclosed power bank no longer has to be used.
